HV0059
HV0059.The horizontal coordinates were scaled from a topographic map and have
HV0059.an estimated accuracy of +/- 6 seconds.
HV0059
HV0059.The orthometric height was determined by differential leveling
HV0059.and adjusted by the National Geodetic Survey in June 1991.
HV0059
HV0059.The geoid height was determined by GEOID99.
HV0059
HV0059.The dynamic height is computed by dividing the NAVD 88
HV0059.geopotential number by the normal gravity value computed on the
HV0059.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
HV0059.degrees latitude (g = 980.6199 gals.).
HV0059
HV0059.The modeled gravity was interpolated from observed gravity values.
